I live in Huntsville, AL. Today I Went to Firehouse subs, they asked for my name, I said "Go Bucks"
I sat at a table, turned out the people sitting next to me were from Sandusky Ohio, we were talking, then the guy yelled "Go Bucks" I raised my hand. The people from Sandusky laughed. The Firehouse guy then said "Roll Tide" I said that's fine as long as it's not Michigan! He agreed, then he laughed and said that was good, you used it to your advantage. As I walked out, the Firehouse guy said "Go Bucks"
I've done that a few times in the area at different locations, normally I don't get much of a response though.
